Irish Guys on holiday in Santa Brabara

Hi

I’m just looking for some friendly advice for things to do while in Santa Barbara. Me and some friends are in our early 20’s and are traveling from Ireland through California for the first time for a few weeks in October and our trip schedule has us stopping off in Santa Barbara on October 17th and 18th. We have always heard of Santa Barbara as a great university town with a huge party scene. We are staying relatively close to the campus and really would just like some advice on some things to see and do while in town. Places to eat? drink? parties? or events on around that time? I’d really appreciate any advice that helps us enjoy the experience a little better, Thanks
